Description

<p>Nippon Paper Industries joined the NEDO project “Technology development of Manufacturing Process for Non-edible Plant-derived Chemicals/Development of an Integrated Process for Manufacturing Chemicals from Woody Biomass”. In this project, we are developing a technology for separating major wood components, cellulose, hemicellulose, and lignin, based on the sulfur-free soda cooking. Lignin is one of the main components in the second most abundant bio-macromolecule after cellulose in nature.</p><p>This work summarizes the outcomes of project, especially product quality of lignins. We provided kg-scale of lignin products to chemical companies which derived from different batch of black liquor. The quality of products listed below, molecular weight, purity, solubility in acetone, and content of functional groups, are stable.</p>
